Yes, but it is a covered walkway that runs from the Carnival Court to past where O'Sheas used to be (it's a concrete skeleton now). It is walkable, but rather unpleasant. The walk can get crowded with people, and it gets direct hot sun in the afternoon. The LVA QOD just did a question on this subject, saying that the sidewalk in front of Margaritaville is about to close too, making this inconvenience even worse. I have no doubt that you can still walk it, but this latest closure will make it even worse.
You might consider changing hotels to Flamingo or Bally's. We are considering changing for our next trip, since we can get a GO room at Flamingo. We love Harrah's (except for their stupid contests and promos), but on our last trip (this month, July), all this almost became too much.
The Carnival Court was running, which means loud recorded music blaring during the day. I didn't hear it at night, because Harrah's knows to put our rooms "AWAY from the Carnival Court." I believe at night they still have live bands. However, I suspect that construction dust might be a concern, since it is outdoors and RIGHT next to the construction. There are still street vendors around the pavillion.
Some positives about Harrah's: Clean rooms, good mattresses; pretty good buffet, much better than Flamingo, but not as good as Paris. Easy valet parking, not affected by construction (or maybe just a little, upon exit). Starbucks. Pleasant, smiling Diamond room where they remember you. And, of course, Big Elvis.
An alternative is to cross the street at Harrah's and do the walk on the other side of the strip (Caesars, Bellagio side), where you get even more hot sun.
